Hybrid tea rose plant named &#39;tan01549&#39;

ABSTRACT

Hybrid tea rose plant for cut flower production having high production of flowers—(240-260 flowers per m2/year) of long lasting flowers (15-18 days).

GENUS AND SPECIES

Rosa hybrida

VARIETAL DENOMINATION

‘TAN01549’

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of hybrid tea rose plant for cut flower production, which was originated by me by cross-breeding two unnamed red hybrid tea rose plants.

BACKGROUND OF THE INVENTION

The primary objective of this breeding was to produce a new rose variety for cut rose production of flowers having a high vase life with good production of flowers per plant.

BRIEF SUMMARY OF THE INVENTION

The objective was substantially achieved, along with other desirable improvements, as evidenced by the following unique combination of characteristics that are outstanding in the new variety and that distinguish it from its parents, as well as from all other varieties of which I am aware:

1. Long lastingness of cut flowers (up to 18 days).

2. High production of flowers: (240-260 flowers per m2/year).

Asexual reproduction of this new variety by cuttings, as performed at Uetersen, Germany, shows that the foregoing and all other characteristics and distinctions come true to form and are established and transmitted through succeeding propagations.

COMPARISON WITH PARENTS

‘TAN01549’ has a longer stem than the mother variety and a darker color of flower than the father variety.

COMPARISON WITH SIMILAR VARIETY

The color of the flowers of ‘TANolorak’ are much darker than those of ‘TAN01549’ and ‘TANolorak’ is perfumed whereas ‘TAN01549’ is not.

BRIEF DESCRIPTION OF THE ILLUSTRATION

The accompanying illustration shows typical specimens of flowers of this new variety depicted in color as nearly true as it is reasonably possible to make the same in a color illustration of this character.
